Have you tried jumping the starter at the solenoid? I don't get what you're saying about the distributor getting power from the solenoid- it should be powered by a circuit that's hot w/the key on or start position. The "IGN" wire at the solenoid was there to bypass the resistor wire on a points-type system only during start up. And the HEI has a coil- that's what's on top of the distributor cap.

You should look at that (above), the ignition switch, and for bad ground circuits.

to be honest it started to do that when i had to replace the battery and altinator. it all started from there. then starter. maybe theres not enough power and a full night of charging hopefully might help. Since there is a new battery and alltinator what do i need for the hei to run propperly? my plastic visa is starting to melt from the friction of slides in the machine. what would be the best solution, to replace all of the ignition system with.... ? i will have to replace bits and pieces eventually why not do the whole thing at once, prevenitive maintance i suppose.

The cost of supplying the HEI w/12 VDC is negligible. You're only talking about a couple terminals and a couple feet of insulated 12-14 gauge primary wire- what, $2.00? I'm a FIRM believer in only replacing parts that need replaced. The "throw parts at it until it works" is for the guys w/too much money and not enough diagnostic skill to do it the 'right' way, IMO.

Was the distributor position in the engine changed for any reason? Are the wires in the correct order, both at the cap and at the plugs? I gave you a link above for that.

Get the battery charged up and then check the coil supply wire for voltage. But if it was starting before, something has happened to f-that up. Try to retrace your steps to see if anything jumps out at you.

Is it still trying to start? You can remove a plug and with the plug wire on the plug and the plug body grounded, see if you get a blue spark at the plug electrode.

The HEI distributor's coil needs to get full battery voltage. The '69 truck originally used a points-type ignition system that used a resistor wire to the coil positive terminal. If this same wire is now being used to supply current to the HEI coil, it will not have the voltage it needs to work right.

So use your voltmeter and w/the coil "+" wire removed, and the key "ON", note the voltage- it needs to be 12 VDC- plus.

problem starting

it still will not start. i have replace spark plugs and wires. charged the battery. checked all fuses. there is fuel going to the carborater. how do i test the distributor by myself? i have a voltmeter. all the electrical conections are tight and in proper order and good working condition. what gives?

hi

ok just alittle more info, sorry for the confusion but its an edelbrock perfermor 1500- 6500 rpm manifold with a edelbrock perfermer 600 cfm carb. delco remy high energy hei ignition.. so i am assuming the 350 came from a 1974 time period or earlier. but has an external regulater from the altinater.

started the truck with pedal to the floor no start but a backfire.
took out the plugs and on the left side if the engine they were wet and on the left side was dry. carbon build up on all but in good shape.

just going to let it sit while i get new plugs, pressure regulator and filter. anything else i should get while im out at auto zombie?

Sometimes just letting it sit for a few hours will allow it to restart if it was flooded.

The routine way of dealing w/a flooded engine at restart is to floor the throttle (w/o pumping it at all!) and hit the key. This allows as much air through as possible.

If no go, take the plugs out and see what they look like. If they're wet, leave them out and crank the engine over a few revolutions and let it sit.

When you get ready to try it again, make sure the plugs are dry before replacing them, and be sure the wires are correct.

What type ignition is on this truck? HEI, points, or ?

The carb "list" number will be stamped into the choke tower.

sorry

by the way it is a 69 chevy c10 with a 350 v8.
